Maximum Active Revenue Recognition Schedules?

I'm working with a client who has a high transactional volume. Many or most of these transactions would require their own revenue recognition schedule; schedule, not template.  I believe they should all be able to use one of two or three Rev Rec Templates, but there is the potential for close to 100k or more than 100k active Rev Rec Schedules.  I am trying to work with them to consolidate these as much as possible, but we still could have 40-50k active schedules.

Is this supported?  The note that comes up when you go to post Rev Rec journal entries ("This preview shows a maximum of 50 schedules...") seems to suggest there might be limitations around the number of schedules; or at the very least the number of schedule JEs that can be posted at once.  If 50 is the limit of Rev Rec schedules that can have their JEs posted at once, that could be an issue as the client would have to run this process hundreds of times.  Has anyone used this many schedules and/or can anyone comment on the feasibility
